mriE  make  the  most  complete  line,  and  our  Jacks  are  better 
adapted  to  all  branches  of  railway  service,  from  track  to 
shops,  and  for  carrying  on  locomotives  and  tool  cars,  than  any 
manufactured  in  the  United  States, 

Jacks  for  special  work,  made  to  order  at  short  notice,  and  at 
reasonable  prices.  All  the  Jacks  we  illustrate  are  made  in 
our  own  shops  and  are  fully  guaranteed. 

Have  you  ever  figured  the  cost  of  maintenance  and  repairs 
on  Hydraulic  Jacks  and  loss  of  their  use  while  in  the  hospi- 
tal ?     If  not,  the  figures  will  astonish  you. 

This  trouble  and  expense  can  be  avoided  by  using  the 
Norton  Ball-bearing  Ratchet  Screw  Jacks. 

We  make  one  claim  only  — The  Norton  Jacks  are  the 
best  in  the  world.

The  Norton  Ball-bearing  Ratchet  and 

Screw  Jacks. 


'^HE  Norton  Ball-bearing  Ratchet  Screw  Jacks  are  constructed 
^  on  an  entirely  different  principle  from  any  other  Jacks  in  the 
world  ;  as  will  be  seen  by  the  cuts,  they  have  a  stationary  standard 
and  sliding  sleeve  fitting  over  the  same.  The  standard  has  a  re- 
movable nut  (usually  Phosphor  Bronze)  fitted  within  it  and  resting 
on  a  shoulder,  in  which  the  screw  turns,  (the  standards  are  hollow, 
and  can  ht  filled  vi'ilh.  oil,  thus  keeping  the  screw  constantly  lubri- 
cated). To  the  upper  end  of  the  screw  is  fastened  a  steel  gear ;  a 
hardened  tool  steel  plate  encircles  the  hub,  and  rests  on  the  body 
of  said  gear,  on  which  are  placed  circular  trains  of  hardened  steel 
balls,  held  in  place  by  rings  between  the  rows  (as  shown  in  cut). 
In  the  top,  or  head  of  the  sliding  sleeve  (which  is  bored  to  fit 
standard),  is  placed  another  hardened  tool  steel  plate  with  a  hole 
in  the  centre,  through  which  the  end  of  the  screw  projects. 

When  the  Jack  is  assembled  the  sleeve  slides  down  over  the 
screw  and  standard,  the  bearing  plate  in  the  head  resting  on  the 
balls  on  the  plate  on  the  gear,  so  that  the  whole  weight  is  carried 
by  the  balls  (between  the  steel  plates),  which  act  as  a  thrust-bear- 
ing betv/een  the  screw  and  head  of  the  sleeve,  reducing  the  friction 
and  increasing  the  lifting  power  of  the  Jack. 

The  sleeve  which  revolves  on  the  standard,  allowins:  the  lever 
to  be  used  from  either  side,  carries  the  load,  and  is  raised  or 
lowered  by  the  screw,  which  is  turned  by  means  of  a  gear  on  the 
rachet  shaft  engaging  with  the  gear  on  the  screw,  and  operated  by 
a  reversible  ratchet  and  lever  having  the  itp  and  down,  or  '"'■pump 
handle^''  motion.  This  is  the  only  screw  Jack  made  having  this 
motion  of  the  lever.  The  sleeve  at  the  lower  end  is  provided 
with  a  '■^ stop  dog'"  or  pawl,  which  prevents  the  screw  from  being 
run  out  of  the  nut. 

The  advantage  of  this  sliding  sleeve  cannot  be  ^7';//- estimated. 
It  takes  all  the  side  strain  off  the  screw,  preventing  it  from  bending, 
and  also  protecting  all  the  working  parts  from  sand,  coal-dirt  and 
water,  making  it  the  only  Jack  suitable  to  carry  on  locomotives. 

All  of  the  Norton  Railroad  Jacks  are  steel  and  malleable  iron 
throughout. 


A.  O.  Norton,  Boston,  Mass.,  U.  S.  A.,  and  Coaticook,  P.  Q.»  Canada. 


Why  We    Claim   the   Norton   Jacks    are 

Superior  to  All  Others,  Especially 

for  Railway  Service. 


Because  of  their  Simplicity,  Durability  and  Cheapness, 

They  are  the  Lightest  Ratchet  Jacks  in  the  world  of  same 
capacity. 

Cost  Less  for  maintenance,  are  always  Safe  and  Reliable, 
even  in  the  hands  of  careless  and  unskilled  workmen,  as  the  screw 
holds  the  load  without  blocking,  and  cannot  drop  or  run  down. 
This  is  a  very  important  feature  in  a  Railway  Jack  and  should  not 
be  overlooked. 

The  screws  are  Self-Lubricating.  Ball-bearings  never  wear, 
and  seldom  need  oiling  or  attention. 

They  can  be  operated  by  ordinary  workmen  without  previous 
instructions. 

They  can  be  left  standing  in  Tool  Car  or  Shop,  or  carried  on 
Locomotives  for  Months  at  a  time  without  any  attention 
whatever,  and  be  found  Ready  for  Service  when  needed,  as 
there  is  no  Alcohol,  Packing  or  Valves  to  keep  in  order. 

All  Parts  are  Interchangeable,  and  can  be  replaced  in  a 
few  minutes  by  ordinary  workmen  at  trifling  cost  without  returning 
to  Factory, 

The  Norton  Journal  Jacks  Weigh  about  one-third  and 
Cost  about  one-fourth  as  much  as  Hydraulics  of  same  capacity, 
ror  same  purpose. 

All  of  our  Screw  Jacks  can  be  used  in  any  position,  fiat  for 
pushing  or  bottom  up,  if  necessary. 

The  cost  for  maintenance  and  repairs  on  all  Jacks  in  use  for 
past  four  years  averages  less  than  i  per  cent,  per  annum. 

We  will  guarantee  to  keep  our  Jacks  in  perfect  working  order 
for  five  years  for  one-half  what  it  costs  for  Alcohol  alone,  for 
.  Hydraulics  of  same  capacity  and  service.

we  will  be  pleased  to  furnish  at  any  time  the  highest  7'eferences,  both

which  gives  more  speed. 

When  full  power  of  Jack  is  required,  use  ratchet  on  Imver  shaft.

These  Jacks  are  intended  for  car  work,  where  long  lift  is  needed,  and  can 
be  used  with  crank  on  empty  cars,  or  light  load,  which  is  much  quicker 
tlian  pumping  up  with  lever.  Another  saving  of  time  is,  the  car  can  be  raised 
and  left  standing  on  the  Jacks  without  blocking,  while  trucks  are 
changed.

NON-BALL-BEARING  JACKS. 


This  cut  shows  construction  of  the  Norton  Jacic 
without  Bail-Bearings. 

Our  Non-Ball-Bearing  Jacks  are  made  on  the  same  principle  as  the  Bail- 
Bearings,  except  the  load  is  raised  by  the  end  of  the  screw,  which  rests  on  a 
haidened  steel  step  <  bushing,  in  the  head  of  the  sliding  sleeve.  Up  to  fifteen 
tons  they  are  as  good  as  the  Bali-Bearing,  except  they  need  a  little  'more 
attention  in  oiling.     All  are  fully  guaranteed. 


\ 


DIRECTIONS  FOR  NORTON  JACK   WITHOUT    BALL-BEARING. 

Keep  working  parts  zuell  oiled.  Take  particular  pains  with  the  top  hole,  as 
all  the  weight  is  borne  on  the  end  of  the  screw.  In  oiling  the  top  hole,  first  fill 
the  hole  with  oil.  Then  raise  the  shell  a  little  to  allow  the  oil  to  settle  well  on 
end  of  Screw.  Do  not  neglect  this  and  74se  plenty  of  oil.  Also  see  that  the 
screw  is  kept  well  oiled.  Keep  gears  well  in  mesh.  To  adjust  gears — Loosen 
four  nuts  on  cap-bolts  and  check  nut  on  set  screw  at  bottom  of  cap.  Turn  set 
screw  till  gears  are  as  close  in  meshes  as  they  will  run  freely.  Then  tighten 
check  nut  on  set  screw  to  hold  gears  in  place,  and  tighten  the  nuts  on  cap-bolts. 
To  take  the  Jack  apart,  take  the  nuts  off  holding  cap,  remove  the  ratchet  and 
gear,  then  lift  the  shell  up,  pressing  bottom  dog  to  let  it  pass  rjroove  in  top 
of  standard.

This  Jack  is  intended  for  carrying  on  locomotives,  for  putting  in  brasses, 
and  yard  work. 

It  can  be  placed  almost  instantly  and  works  very  rapidly.  The  screw 
being  protected,  it  never  gets  rusty  and  useless  from  exposure  on  the  engine, 
as  is  so  often  the  case  with  common  Bottle  Jacks,  but  is  always  ready  for 
use.  ^ 

Brasses  can  be  changed  in  half  the  time,  and  much  easier,  than  witli  the 
old  style  Jack. 

Every  Car  Inspector  Should  Have  One^

These  Jacks  are  made  of  malleable  iron  and  steel  throughout,  with  phosphor 
bronze  nut,  same  as  all  our  ball-bearing  Railway  Jacks. 

Instead  of  ball  bearings,  the  end  of  screw  is  conical  shape,  working  on  a 
•removable,  hardened  steel  plate,  fitted  in  the  head  of  sliding  sleeve.  In  case 
■of  wear,  this  plate  can  be  replaced  at  slight  expense. 

Where  a  very  serviceable  and  Icnv-priced  Jack  from  10  to  15  fous,  capacity, 
'is  required,  this  pattern  cannot  be  excelled ;  fully  guaranteed.

respects  suitable  for  general  service.

These  Jacks  are  designed  for  use  in  car  repair  shops,  street  railway  service, 
mills,  stone  yards  and  quarries,  for  truckmen  and  machinery  movers. 
They  are  built  for  speed,  and  with  the  crank,  light  loads  can  be  raised  or 
lowered  very  rapidly,  while  heavy  weights  are  easily  raised  with  the  ratchet  and 
lever. 

Tn  addition  to  the  crank,  we  send  free  with  each  Jack,  a  tool  steel  pinch 
bar,  which  will  be  found  very  convenient. 

Both  the  Car  and  Stone  Jacks  are  made  compound  or  double  geared. 
Fig.  I  represents  the  compound  geared  Car  Jack,  broad  base.  Fig.  2 
represent.s  the  double  geared  Stone  Jack.  All  have  forged  sleei  lifting  bar, 
cut  teeth  and  steel  gears.

A.  O.  Norton,  Boston.  Mass.,  U.  S.  A.,  and  Coatlcook,  P.  Q.,  Canada. 


The  Norton   **Sure  Drop"  Track  Jack, 


DESCRIPTION. 


The  body  of  the  Jack  is  of  malleable  iron,  made  in  two  pieces,  the  sides 
and  bearings  of  each  part  being  accurately  milled,  joined  together  and  firmly 
riveted  above  the  foot,  which  is  in  one  piece,  making  a  Strong,  solid  base. 
The  lifting  bar  is  made  from  best  quality  forged  steel,  milled  to  fit  body 
of  Jack,  with  teeth  cut  on  two  sides,  one  for  lifting  and  one  for  holding 
pawl.  The  teeth  in  lifting  side  of  bar  are  cut  square  on  top,  making  it  im- 
possible for  pawl  to  become  disengaged  while  lifting. 

The  mechanism  for  lifting  consists  of  a  cam  on  end  of  lever  socket  3 
(see  cut  3),  working  in  strap  which  carries  lifting  pawl  6.  Strap  and  cam  are 
bored  and  turned  to  fit,  and  hardened.  The  cam  turns  on  a  ^  inch 
hardened  tool  steel  pin,  which  is  keyed  to  frame  so  it  cannot  turn. 
The  cam  has  sufficient  throw  to  raise  the  bar  >^'  inch,  i  inch,  or  i>^  inches,  as 
may  be  desired,  with  one  stroke  of  the  lever. 

The  teeth  on  holding  side  of  bar  are  cut  in  line  with  an  arc  of  a 
circle  struck  from  centre  of  pin  in  holding paivl  4  (see  cut).  Hinged  to  hold- 
ing pawl  4,  is  tripping  cam  5. 

To  raise,  turn  tripping  cam  to  left  (see  fig.  i). 

To  trip  the  Jack  it  is  only  necessary  to  turn  tripping  cam  into  posi- 
tion as  shown  in  cut.  2,  raise  the  lever  and  turn  lifting  pawl  back. 
Pressing  down  on  the  lever  brings  the  end  of  lever  socket  in  contact  with 
tripping  cam  5,  forming  a  wedge,  whi.h  in  combination  with  the  shape  of 
the  teeth  on  lifting  bar,  before  mentioned,  is  so  powerful  that  a  man  can 
easily  and  instantly  trip  with  one  hand,  any  load  that  can  be  raised 
with  the  Jack,  even  with  two  or  three  men  on  the  lever.

CLAinS. 

We  claim  that  the  "  Norton  "  is  the  most  perfectly  made  track  Jack 
in  the  market.  Our  lifting  device  is  the  easiest,  quickest  working  and 
most  powerful  ever  applied  to  any  track  Jack.  Our  tripping  device 
is  perfect.  It  is  not  necessary  to  lift  the  load  before  it  can  be  dropped, 
as  with  other  Jacks.  There  are  less  parts  to  wear  and  keep  in  repair, 
and  each  part  can  be  duplicated. 

The  wear,  if  any,  being  on  the  cam  (which  is  protected  from  the  sand  and 
grit  by  the  strap)  is  distributed  over  so  much  surface,  that  it  cannot  inter- 
fere with  the  working  of  the  Jack,  while  the  perfect  fitting  of  the 
parts  is  a  great  improvement  over  other  Jacks  which  are  nearly  all  made  from 
castings  put  together  in  the  rough,  with  the  lifting  pawls  hinged  on  small 
pins. 

In  a  word,  we  claim  the  "  Norton  "  Jacks  are  the  nearest  perfection  of 
any  tools  of  the  kind  ever  produced.
